When is Humalog insulin typically administered?

Humalog insulin is a rapid-acting insulin that is typically administered with meals to help control postprandial blood glucose levels. Its onset of action is about 15 minutes, peaks in about 1 to 2 hours, and has a duration of action of around 3 to 5 hours. Therefore, when given with meals, it effectively manages the rise in blood sugar that occurs after eating by facilitating the uptake of glucose into the cells and decreasing blood glucose levels.

Using Humalog in this manner ensures that insulin is present when the body needs it most for managing carbohydrate intake, thereby reducing the risk of hyperglycemia. Administering it at other times, such as before bedtime or after meals, may not provide the desired control over post-meal glucose levels.
